Ultra-Long Blade Solution 3200–3600mm Large Paper Mill Exclusive
Custom Linear Grinder for Large Paper Mill Blades
2026-08-12
Large-scale paper mills and large-format printing factories widely use ultra-long guillotine blades and wide-width slitter blades above 3000mm. However, most ordinary grinding machines on the market cannot adapt to ultra-long blade grinding. The problems of insufficient stroke, unstable clamping, poor straightness, and easy deformation have long plagued large paper enterprises. To solve the grinding pain points of ultra-long paper blades, we launched a customized ultra-large CNC Electromagnetic Linear Knife Grinder, specially serving large paper mills and large-format printing and packaging enterprises.
This customized ultra-long grinder is fully optimized for 3200mm, 3400mm, and 3600mm super-long paper blades. The lengthened integralelectromagnetic chuck covers the full length of the ultra-long blade, realizing full-surface uniform adsorption and fixing. Compared with segmented clamping and short-stroke repeated grinding of ordinary machines, our one-piece forming grinding completely avoids blade overall torsion and local unparallel errors, ensuring that the straightness and flatness of ultra-long blades reach industrial high-precision standards.
The lengthened high-rigidity linear guide rail and reinforced servo drive system ensure stable and synchronous operation of the long-stroke grinding head without jitter or deviation. The CNC system is upgraded with ultra-long stroke calibration program to ensure consistent grinding depth from the blade head to the tail. The whole blade edge is smooth and uniform, which perfectly matches the high-precision cutting requirements of large-format paper machines and wide-web printing equipment.
In addition to standard ultra-long models, we support fully personalized customization according to customer’s super special blade length, blade thickness, and grinding process requirements. The reinforced thickened steel body structure enhances the overall stability of the equipment, adapting to 24-hour continuous high-load industrial operation. The high-flow circulating water cooling system ensures uniform temperature control of ultra-long blades, effectively preventing local annealing and hardness inconsistency.
For large paper manufacturing groups and large-format printing enterprises with ultra-long blade maintenance needs, ordinary standard grinders cannot meet production standards. This customized ultra-long CNC Electromagnetic Linear Knife Grinder fills the market gap of high-precision grinding for super-long paper blades, helping large enterprises stabilize high-end product quality and maintain leading market competitiveness.
